Gastroduodenal artery aneurysm - an extremely rare but insidious cause of abdominal pain: a case report.

An arterial aneurysm is a localized weakening of the artery wall that results in pathological dilatation. All intra-abdominal artery aneurysms are labeled as visceral artery aneurysms (VAA), apart from the aorto-iliac artery aneurysms. VAA´s are rare, gastroduodenal artery aneurysms (GDAA), constituting 1.5% of visceral artery aneurysms. A woman in her early 80s´ presented with chronic epigastric pain, weight loss, and nausea. Conservative management was unsuccessful. Imaging revealed a GDAA, prompting endovascular coil embolization. Subsequent evaluation confirmed Polyarteritis Nodosa (PAN), treated with rituximab. The report underscores the diagnostic challenges, emphasizing the need for a multidisciplinary approach using imaging and angiography. GDAA's potential life-threatening rupture necessitates prompt intervention, as illustrated in this case. The rare association with PAN, although infrequent, underscores the importance of considering underlying etiologies in multiple visceral aneurysms. Early diagnosis and intervention are pivotal for this uncommon yet potentially lethal condition.

Rare and potentially lethal case of a round lesion in the lung.

A pulmonary venous aneurysm (PVA) is extremely rare. A PVA can be either congenital or acquired. Possible symptoms include thoracic pain, dyspnoea, haemoptysis and palpitations but can also occur asymptomatically. Treatment can be conservative or surgical depending on growth and risk of rupture or development of mitral insufficiency, symptoms and thrombus formation. Only a few cases have been described in the literature. A recent case study and a literature review are described below.

A Unique Case Of A Giant Popliteal Artery Aneurysm Presenting As Popliteal Mass.

INTRODUCTION: Popliteal artery aneurysms (PAA) can be very challenging, especially in cases of very large PAAs, with a minimal number of case reports published in the literature. METHODS: This is a case report of a 68-year-old male patient with hypertension, hyperlipidemia, diabetes, and schizophrenia who was found to have a giant (10x8x6cm) partially thrombosed PAA, treated with interposition polytetrafluoroethylene (PTFE) graft via a posterior approach. RESULTS: Under general anesthesia, the patient was placed in a prone position, and an extended lazy "S" incision was made on the popliteal fossa. After obtaining proximal and distal exposure, the aneurysm sac was skeletonized, preserving the popliteal vein and the tibial nerve. After proximal and distal control was obtained, the patient was systemically heparinized, and the aneurysm sac was opened. Some genicular branches were ligated inside the aneurysm, and part of the aneurysm sac was excised. A 7 mm PTFE graft was used for reconstruction in an end-to-end fashion. Suction drains were placed in the popliteal space, and the fascia and skin were approximated. The patient was discharged home on the 2nd postoperative day on aspirin and statin with ultrasound surveillance. The patient has remained asymptomatic during follow-up with a patent graft. CONCLUSIONS: Open surgical repair constitutes the gold standard of care for huge PAAs to prevent distal thromboembolic events and mass pressure effects from the aneurysm. Documentation of additional experience with open repair of huge PAAs would be beneficial and could help clinical decision-making.

Enlarging aneurysm with paracentral acute middle maculopathy in idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) - a case report.

INTRODUCTION: Idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome is a rare clinical entity affecting young healthy individuals. Treatment primarily involves pan retinal photocoagulation (PRP) to capillary non perfusion areas. Intravitreal anti-VEGF or steroids are given in the presence of macula edema. Oral steroids do not alter the course of the disease. Arterial occlusions have been reported in IRVAN. METHODS: Retrospective case review. RESULT: A twenty seven year old male presented to us with mild blurring of vision for one week. His BCVA was OU 20/20. Anterior segment examination was normal. Fundus examination showed bilateral disc aneurysm with OS arterial aneurysm along the inferior arcade. Fundhus fluorescein angiography and OCT angiography were confirmatory of the disc and retinal aneurysm. Capillary non perfusion (CNP) areas were noted in the periphery. Two days later he presented with paracentral scotoma in his left eye which was confirmed by Amsler chart. Fundus, OCT and OCTA were confirmatory of Paracentral Acute Middle Maculopathy (PAMM). The retinal aneurysm had increased in size from 333 micron diameter to 566 micron diameter. Panretinal photocoagulation to the CNP areas was done and intravitreal antiVEGF was given. At 6 months follow up, retinal aneurysm had disappeared. DISCUSSION: Our case describes a unique event with sudden increase in size of the aneurysm leading to acute blockage in the deep capillary plexus thus being the first report of PAMM in IRVAN. The patient was treated with PRP and intravitreal anti-VEGF for the enlarging aneurysm which reduced in size within a week.

Hughes-Stovin syndrome-An important differential diagnosis in patients with suspected chronic thromboembolic pulmonary hypertension : A case report.

Hughes-Stovin syndrome (HSS) is a rare vasculitis of unknown etiology. The disease is characterized by pronounced inflammation and damage to the vessel walls, with subsequent widespread vascular thrombosis and the formation of pulmonary artery aneurysms that can lead to fatal hemoptysis. This disorder can be mistaken for other conditions, such as chronic thromboembolic pulmonary disease (CTEPD) without or with pulmonary hypertension at rest (CTEPH).We report the case of a 20-year-old female with HSS, which was misdiagnosed as CTEPH and subsequently treated with anticoagulants, which led to severe hemoptysis and eventually death of the patient. This case highlights the challenges of diagnosing HSS at early stages of the disease.HSS should be considered in young patients with signs of large vessel vasculitis in combination with thrombotic occlusions of pulmonary arteries, with or without aneurysms of the pulmonary arteries, and particularly, if there are no risk factors for thromboembolic disease.

Outcomes following surgical and endovascular treatment of extracranial vertebral artery aneurysms (VAA): a systematic evaluation of the literature.

Extracranial vertebral artery aneurysms are rare complications resulting from trauma and multiple different diseases. However, the difference between clinical and surgical profiles is well understood. To investigate the clinical and interventional outcomes following extracranial vertebral artery aneurysms (VAA) treatment through a systematic review of the literature to date, an electronic database search for full-text English articles was conducted following PRISMA guidelines. The search yielded results on clinical and surgical outcomes for extracranial VAAs. These results included patient-specific risk factors, indications, and techniques. Our literature search resulted in 561 articles, of which 36 studies were qualified to be included in the analysis. A total of 55 patients with multiple various extracranial VAA incidents were included. The mean age of subjects was 42 years (ranging from 13.0 to 76.0 years), and the majority of patients were males (71%, n =39). Blunt trauma was the most frequent risk factor for extracranial VAA formation (35%, n = 19). The majority of aneurysms (60%) were dissected in nature. The most common form of treatment for extracranial VAAs was the use of a flow diverter (24%, n=13). Overall, five (9%) patients had long-term adverse neurological complications following intervention with 5% (n=3) mortality, 2% (n=1) resulting in unilateral vocal cord paralysis, and 2% (n=1) resulted in a positive Romberg sign. The mortality rate is 15.7% in the surgical group, whereas the endovascular treatment did not result in any mortality. The endovascular approach is a safe and effective treatment of extracranial VAAs due to its relatively low overall complication rate and lack of resulting mortality. This is in contrast to the surgical approach which results in a higher rate of complications, recurrence, and mortality outcomes. An understanding of the factors and clinical outcomes associated with the incidence of extracranial VAAs is essential for the future improvement of patient outcomes.

[Diagnostic and treatment options for retinal arterial macroaneurysms in relation to our cases]. / Retinalis artéria macroaneurysmák diagnosztikai és kezelési lehetoségei eseteink kapcsán.

In our report, we present the history of four patients diagnosed with retinal arterial macroaneurysm associated with complications. Our aim is to present the varied appearance of the disease and to present the various therapeutic options. Retinal artery macroaneurysm is a rare, but potentially vision-threatening ophthalmic condition. Macroaneurysm develops from the arteriosclerotic transformation of the artery caused by high blood pressure. Macroaneurysms can be asymptomatic, or they can be associated with exudative or hemorrhagic complication which causes visual impairment. Depending on the symptoms, they can be treated with laser photocoagulation, intravitreal injections, or with vitrectomy. Our presented cases also illustrate that each case requires individual consideration because a uniform therapeutic recommendation is still yet to be developed. In addition to the ophthalmic treatment, it is extremely important to refer the patient to internal medicine. Orv Hetil. 2023; 164(42): 1673-1677.

Current Approaches for Mesenteric Ischemia and Visceral Aneurysms.

This article provides an overview of acute mesenteric ischemia, chronic mesenteric ischemia, and visceral aneurysms, with a focus on treatment. Acute mesenteric ischemia can be a challenging diagnosis. Early recognition and adequate revascularization are key to patient outcomes. Chronic mesenteric ischemia is a more insidious process, typically caused by atherosclerosis. Various options for revascularization exist, which must be tailored to each patient. Visceral aneurysms are rare and the natural history is not well defined. However, given the risk of rupture and high mortality, treatment may be complex.

An Epithelioid Hemangioma Camouflaged As Radial Aneurysm.

Epithelioid hemangioma (EH) is an uncommon benign vascular lesion usually present as subcutaneous nodules in the head and neck area. Sometimes, these lesions can occur in the peripheral arteries, and when they do, they can be mistaken for aneurysmal dilatations of that respective vessel. We report a case of a 43-year-old male who underwent surgical recession of a radial aneurysm, which after anatomopathological examination, revealed an EH.

Successful Medical-Surgical Management of Intracardiac Thrombosis and Pulmonary Pseudoaneurysms in an Adolescent With Hughes-Stovin Syndrome.

We present an adolescent male with a single intracardiac mass and pulmonary emboli, complicated by peripheral venous thrombosis and subsequent development of pulmonary pseudoaneurysms, leading to diagnosis of Hughes-Stovin syndrome. Remission was achieved with cyclophosphamide, corticosteroids, and pseudoaneurysm resection and maintained with infliximab and methotrexate.

Endovascular embolization of visceral artery aneurysm: a retrospective study.

To assess the safety and efficacy of endovascular embolization techniques, we compared the short- to medium-term prognosis of coil embolization for symptomatic visceral aneurysms (SVAA) and asymptomatic visceral aneurysms (ASVAA) to identify risk factors associated with 30-day mortality. Explore the symptom profile and intrinsic associations of SVAA. A retrospective study of 66 consecutive patients at two tertiary care hospitals from 2010 to 2020 compared the short- to mid-term outcomes of 22 symptomatic VAAs and 44 asymptomatic VAAs treated with coil embolization. Univariate and log-rank tests were used to analyze the prognostic impact of SVAA and ASVAA. SVAA group had significantly higher 30-day mortality than ASVAA group (2(9.1%) vs 0, P = 0.042), both patients who died had symptomatic pseudoaneurysms. Perioperative complications such as end-organ ischemia (P = 0.293) and reintervention (P = 1) were similar in both groups. No difference in event-free survival was identified between the two groups (P = 0.900), but we found that the majority of pseudoaneurysms were SVAA (4/5) and that they had a much higher event rate than true aneurysms. In addition, dyslipidemia may be an influential factor in the development of VAA (P = 0.010). Coil embolization is a safe and effective method of treatment for VAA. Most pseudoaneurysms have symptoms such as abdominal pain and bleeding, and in view of their risk, more attention should be paid to symptomatic patients and the nature of the aneurysm should be determined as soon as possible to determine the next stage of treatment.

Association Between the Degree of Severity of Pulmonary Hypertension With the Presence of Pulmonary Artery Aneurysm: A Brief Updated Review for Clinicians.

Pulmonary hypertension (PH) is defined as an increase in mean pulmonary arterial pressure (mPAP) ≥20 mm Hg at rest as assessed by right cardiac catheterization. It has a median survival nowadays of 6 years, compared to 2.8 years in the 1980s. A pulmonary artery aneurysm (PAA) is the focal dilation of a blood vessel involving all 3 layers of the vessel wall; they have a diameter greater than 4 cm measured in the trunk of the pulmonary artery. PAAs can be classified into proximal (or central) and peripheral. The clinical manifestations of PAA are primarily nonspecific, and most patients remain undiagnosed, even those with large PAA, due to its silent course; however, clinical manifestations occur unless when there are complications such as bronchial or tracheal compression (leading to cough and dyspnea), dissection, or rupture (leading to hemoptysis). PAH is observed in 66% of patients with PAA. PA dissections are usually associated with PAH; 80% of dissections occur in the main pulmonary trunk. Although there is no clear guideline for the best treatment of PAA, surgery is indicated in patients with a pulmonary trunk aneurysm >5.5 cm. It has been observed that patients in the PAH group associated with congenital heart disease tend to develop PAA more commonly. Those with PAH associated with connective tissue disease have a smaller diameter of PA dilation. This report presents a comprehensive review of PAA, discussing critical aspects of the clinical and imaging diagnosis, hemodynamics, and treatment. A comprehensive updated literature review is included; we believe this article will interest cardiopulmonologists.

Frail Silk: Is the Hughes-Stovin Syndrome a Behçet Syndrome Subtype with Aneurysm-Involved Gene Variants?

Hughes-Stovin syndrome is a rare disease characterized by thrombophlebitis and multiple pulmonary and/or bronchial aneurysms. The etiology and pathogenesis of HSS are incompletely known. The current consensus is that vasculitis underlies the pathogenic process, and pulmonary thrombosis follows arterial wall inflammation. As such, Hughes-Stovin syndrome may belong to the vascular cluster with lung involvement of Behçet syndrome, although oral aphtae, arthritis, and uveitis are rarely found. Behçet syndrome is a multifactorial polygenic disease with genetic, epigenetic, environmental, and mostly immunological contributors. The different Behçet syndrome phenotypes are presumably based upon different genetic determinants involving more than one pathogenic pathway. Hughes-Stovin syndrome may have common pathways with fibromuscular dysplasias and other diseases evolving with vascular aneurysms. We describe a Hughes-Stovin syndrome case fulfilling the Behçet syndrome criteria. A MYLK variant of unknown significance was detected, along with other heterozygous mutations in genes that may impact angiogenesis pathways. We discuss the possible involvement of these genetic findings, as well as other potential common determinants of Behçet/Hughes-Stovin syndrome and aneurysms in vascular Behçet syndrome. Recent advances in diagnostic techniques, including genetic testing, could help diagnose a specific Behçet syndrome subtype and other associated conditions to personalize the disease management.

[Hybrid treatment of Kommerell diverticulum and giant aneurysm of intra-thoracic segment of aberrant left subclavian artery]. / Klinicheskii sluchai gibridnogo lecheniya divertikula Kommerelya i gigantskoi anevrizmy vnutrigrudnogo segmenta aberrantnoi levoi podklyuchichnoi arterii.

Kommerell's diverticulum causes compression of the esophagus, trachea and laryngeal nerve between the aberrant mouth of the left subclavian artery and ascending aorta. This leads to dysphagia or shortness of breath. We describe hybrid treatment of the right aortic arch with Kommerell's diverticulum and giant aneurysm of the aberrant left subclavian artery.

Combined endovascular and surgical treatment of a giant celiac artery aneurysm with consequent gastric outlet obstruction: a case report and literature review.

BACKGROUND: Visceral artery aneurysms (VAA) are rare with an incidence of up to 0.2% and mortality of up to 40%. Aneurysms larger than 5 cm are referred to as giant visceral artery aneurysms (GVAA). We present a case of a celiac artery aneurysm of 14 cm which required endovascular and surgical management. A review of the literature with focus on treatment is also provided. CASE PRESENTATION: In this case report, a 76-year-old male presented with postprandial nausea and vomitus. An ultrasound and computed tomography scan showed an aneurysm of the celiac artery of approximately 14 cm. Initial treatment was conducted with coiling. Despite this treatment, patient presented again with the same complaints, most likely due to gastric outlet syndrome caused by the aneurysm sac. Partial open removal of the aneurysm sac was performed with release of the duodenum. Due to recurring dysphagia and postprandial nausea, a gastroenterostomy was created, which was later supplemented with a Roux-en-Y anastomosis due to gastroparesis. Patient recovered uneventful after the Roux-en-Y and was discharged from the hospital. CONCLUSION: Giant visceral artery aneurysms sometimes need multimodal treatment. We showed that an endovascular first approach of a giant visceral artery aneurysm is not only technically feasible, but it also facilitates subsequent open surgery due to limiting blood loss and reducing the need for extensive mobilisation of the viscera to gain arterial control.
